Don't bother with SWF, many devices (e.g Tablets) can't read the Flash format.
Thanks Derek, I know Flash is ancient stuff, but I am asked to do like this, unless we persuade the client to choose another way
Or maybe, I could merge all indd docs into one, but how?
You can drag and drop pages from the pages panel. Set View Pages from the Page panel flyout to Vertically (so they don't come in as alternate layouts), then select all the page thumbnails and drag them to the destination document. You'll get a dialog asking where to start the incoming pages.
Thanks Rob, I thought there would be a faster way but I'm gonna try this.
Have a nice day!
